The ATP tour is witnessing a quiet yet poignant farewell wave, as players in their mid-to-late 30s and nearing 40 are gradually saying goodbye. Swiss veteran Stan Wawrinka announced earlier this year that 2026 would be his final season, French showman Gaël Monfils plans a farewell match at the upcoming French Open, and now, Japanese star Kei Nishikori has officially declared his retirement on social media.
Nishikori’s name has been absent from headlines for a while, but his legacy remains significant. He was the first Asian male player—after Thailand’s Paradorn Srichaphan—to break into the world’s top 10, and his finest hour came over a decade ago. At the 2014 US Open, he stormed through the draw, defeating three top-10 players, including a prime Novak Djokovic in the semifinals, becoming the first Japanese man to reach a Grand Slam singles final. Although he lost to Marin Čilić in the final, he had stood at the pinnacle, forcing the world to recognize the potential of Asian men’s tennis.
In 2015, he reached a career-high ranking of world No. 4. At the 2016 Rio Olympics, he defeated Rafael Nadal in three sets to claim the bronze medal, another historic first. Back then, his footwork was swift, his strokes crisp, like a sharp samurai blade. Unfortunately, professional tennis offers no straight upward trajectory. Persistent wrist, back, and hip injuries plagued him, and his ranking steadily dropped. His last appearance in the top 10 was in autumn 2019. After that, his name gradually faded from the front pages, as if gently set aside by time.
“Looking back at everything so far, I can proudly say I gave it my all,” Nishikori wrote in his retirement announcement. He tasted the joy of victory, the bitterness of defeat, and fought through injuries to honor his love for the sport. Now, at 36, he has accepted his fate, closing a long journey with a quiet, graceful finish.
Born in Shimane Prefecture, Japan, Nishikori started playing tennis at age five. He moved to the United States for training at 13, turned professional in 2007, and won his first ATP title at the Delray Beach International Tennis Championships in 2008 at just 18. Eighteen years later, he has chosen to stop. The bittersweet truth rings again: no one stays 18 forever, but someone is always 18.
Over the past decade plus, the men’s tour has seen constant comings and goings. Veterans fade, new names emerge. Players like Nishikori, who once tore through the cracks of the Big Four’s dominance and made history, will be remembered.
When Nishikori first rose to prominence, Uniqlo signed him as a global brand ambassador, marking a key starting point for the brand’s tennis narrative—a homegrown top player became the gateway for Uniqlo’s entry into global sports. Later, from Novak Djokovic to Roger Federer and young Emma Raducanu, this path continued, even extending to officials wearing LifeWear on court, broadening the brand’s connection with tennis.
Statistically, Nishikori leaves behind an impressive resume: 12 ATP titles, over $26 million in prize money, and an immeasurable impact. Like two-time Grand Slam champion Li Na, Nishikori was a crucial figure in tennis’s breakout in Asia over the past decade. Even today, Asian men’s tennis is still chasing the heights he once reached.
